Non-right angled trigonometry extends the principles of trigonometry to triangles that do not contain a 90-degree angle. This introduces new challenges and requires a deeper understanding of trigonometric relationships. The Cosine Rule, a fundamental theorem in non-right angled trigonometry, provides a powerful tool for solving a wide range of triangle problems.

The Cosine Rule, also known as the Law of Cosines, is a generalization of the Pythagorean Theorem. It states that in a triangle with sides of lengths a, b, and c, and an angle θ opposite side c, the following equation holds:

c² = a² + b² - 2ab cos(θ)
